| 摘 要： | 染色体核型分析表明,膜荚黄芪[Astragalus membranaceus(Fisch.)Bge.]和蒙古黄芪[Astragalus membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao]均为二倍体,2n=2x=16,第8号染色体上均有随体;膜荚黄芪核型为2n=2x=8m(1SAT) 8sm,蒙古黄芪染色体核型为2n=2x=6m 10sm(1SAT);核型对称性分别为2A和2B型.该结果支持<中国植物志>关于蒙古黄芪为膜荚黄芪变种的观点.

| Abstract: | Karyotype of Astragalus membranaceus was carried out in this paper.The results showed that A.membranaceus Bge.and A.membranaceus.var.mongholicus(Bge.)Hsiao both were diploid,2n=2x=16,and there was satellite in the 8th chromosome of two Astragalus;karyotype of A.membranaceus Bge.was:2n=2x=8m(1SAT) 6sm 2st,karyotype of A.membranaceus.var.mongholicus(Bge.)Hsiao was: 2n=2x=6m 10sm(1SAT);the karyotype of two Astragalus was belonged to Stebbins' 2A and 2B type respectively,and the opinion of Chinese Flora that A.membranaceus.var.mongholicus(Bge.)Hsiao was the variation of A.membranaceus Bge.was supported. |
